a4184174 - alpha: drop pre-EV56 support

Wed, 13 Dec 2023 17:00:54 +0000

alpha: drop pre-EV56 supportAll EV4 machines are already gone, and the remaining EV5 based machinesall support the slightly more modern EV56 generation as well.Debian only supports EV56 and later.Drop both of these and build kernels optimized for EV56 and higherwhen the "generic" options is selected, tuning for an out-of-orderEV6 pipeline, same as Debian userspace.Since this was the only supported architecture without 8-bit and16-bit stores, common kernel code no longer has to worry aboutaligning struct members, and existing workarounds from the blockand tty layers can be removed.The alpha memory management code no longer needs an abstractionfor the differences between EV4 and EV5+.Link: https://lists.debian.org/debian-alpha/2023/05/msg00009.htmlAcked-by: Paul E.

ce697cce - kbuild: remove head-y syntax

Sat, 24 Sep 2022 18:19:15 +0000

kbuild: remove head-y syntaxKbuild puts the objects listed in head-y at the head of vmlinux.Conventionally, we do this for head*.S, which contains the kernel entrypoint.A counter approach is to control the section order by the linker script.Actually, the code marked as __HEAD goes into the ".head.text" section,which is placed before the normal ".text" section.I do not know if both of them are needed. From the build systemperspective, head-y is not mandatory. If you can achieve the proper codeplacement by the linker script only, it would be cleaner.I collected the current head-y objects into head-object-list.txt. It isa whitelist. My hope is it will be reduced in the long run.Signed-off-by: Masahiro Yamada Tested-by: Nick Desaulniers Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/alpha/Makefile

8212f898 - kbuild: use more subdir- for visiting subdirectories while cleaning

Wed, 13 Oct 2021 06:36:22 +0000

kbuild: use more subdir- for visiting subdirectories while cleaningDocumentation/kbuild/makefiles.rst suggests to use "archclean" forcleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.Since commit d92cc4d51643 ("kbuild: require all architectures to havearch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick forall architectures. This can take advantage of the parallel option (-j)for "make clean".I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep"target no longer exists.Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc) List of files: /linux-6.15/arch/alpha/Makefile

kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIGUntil recently, if KBUILD_DEFCONFIG was not set by the arch Makefile,the default path arch/*/defconfig was used.The last users of the default are gone by the following commits:- Commit f3e20ad67b4c ("s390: move arch/s390/defconfig to arch/s390/configs/defconfig")- Commit 986a13769c4b ("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig")Let's set arch/*/configs/defconfig as a new default.

1f2f01b1 - kbuild: add machine size to CHECKFLAGS

Wed, 30 May 2018 20:48:38 +0000

kbuild: add machine size to CHECKFLAGSBy default, sparse assumes a 64bit machine when compiled on x86-64and 32bit when compiled on anything else.This can of course create all sort of problems for the other archs, likeissuing false warnings ('shift too big (32) for type unsigned long'), orworse, failing to emit legitimate warnings.Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT,to CHECKFLAGS in the main Makefile (and so for all archs).Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.Signed-off-by: Luc Van Oostenryck Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/alpha/Makefile

ede42692 - alpha: link failure fix

Fri, 20 Jun 2008 23:26:21 +0000

alpha: link failure fixWith built-in scsi disk driver, the final link fails with a followingerror:`.exit.text' referenced in section `.rodata' of drivers/built-in.o:defined in discarded section `.exit.text' of drivers/built-in.oThis happens with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE=y) with all gcc-4versions, and also with -O2 and gcc-4.3.The problem is in sd.c:sd_major() being inlined into __exit functionexit_sd(), and the compiler generating a jump table in .rodata sectionfor the 'switch' statement in sd_major(). So we have references todiscarded section.Fixed with a big hammer in the form of -fno-jump-tables.Note that jump tables vs. discarded sections is a generic problem,other architectures are just lucky not to suffer from it. But witha slightly more complex switch/case statement it can be reproducedon x86 as well. So maybe at some point we should consider-fno-jump-tables as a generic compile option...Signed-off-by: Ivan Kokshaysky Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/alpha/Makefile

We can create a separate "historical" gitarchive of that later if we want to, and in the meantime it's about3.2GB when imported into git - space that would just make the earlygit days unnecessarily complicated, when we don't have a lot of goodinfrastructure for it.Let it rip!
